CHICAGO, Aug. 12 - More than one in 10 patients who underwent heart bypass
operations were readmitted to a hospital within a month in a study published
Tuesday, and researchers said among the risk factors were the surgeon's
level
of experience.
Overall, 13 percent of the 16,000 people who underwent coronary artery
bypass graft surgery in New York state in 1999 were readmitted to hospitals
within a month due to complications from the operation, the study published
in
the Journal of the American Medical Association said. Nearly 3 percent of
the
readmitted patients died.
Infections and heart failure accounted for nearly half the readmissions
blamed on complications from bypass surgery, with older patients, women and
blacks all at higher risk of being back in the hospital within 30 days.
''It was troubling to see that that high a percentage of patients did
need to be readmitted for complications of surgery,'' said study author Dr.
Edward Hannan of the University at Albany, State University of New York.
''These complications cost money to the hospitals and the health care
system and certainly they cause a lot of harm to patients as well,'' he
said.
Hannan said the study's findings mirrored previous findings that showed
improved outcomes when the surgery was performed at high-volume hospitals
and
by surgeons who did more than 100 such operations annually.
Refining these measures of effectiveness could help patients choose the
best care and caregivers reduce readmission rates, he said.
